How to fix when faces points on a disc are out of sync?
It usually means that it’s number of vertices is different compared to the other faces.
If you add a vertex to one edge (i.e by subdividing the edge), the dot in the centre of the face moves towards the extra vertex.

I don’t know what you did because I can’t look at your file, but you should know that in no way does this affect your final render… these dots only show in Edit Mode.

First you need to have a look at it in ‘Vertex select’ mode by selecting the first (left) of the three buttons on the header, directly below the 3D Viewport. 

If you see an extra vertex (like the one highlighted on the right of my original screen shot), then select it and delete (press X, and choose ‘Dissolve Vertices’).

Another way to check is to select the face while in ‘Face select’ mode…

and check the number of Verts indicated in the top header, above the 3D Viewport.

The one I made has one extra vertex so it tells me: Verts:4/24 (4 Verts selected out of a total of 24 on the object. It should, of course, have only 3, being a triangle.
